||=== Build finished: 7 errors, 8 warnings ===|
The code contains multiple errors such as passing variables of the wrong type to functions, function definitions that differ from their previous declaration, assignment of variables with an incompatible type etc. It's simply not possible to tell you how to fix the code since this is too much code, too many errors and too few explanation.
I recommend you changing your style of working: Write a few lines of code and compile it. Then fix all the errors the compiler complains about. If possible test the compiled program. Then add a few more lines of code and repeat the above steps.
By working in smaller steps, you'll more likely be able to fix the errors yourself, mainly because it's just one or two errors to fix. Even if you can't fix it, the StackOverflow community will then be able to tell you what the cause and the possible fix for the error is.
But refrain from writing hundreds of lines of code without compiling them. Once you have accumulated so many errors, is almost impossible to isolate and fix them.
Lots of problems in this code, but you knew that.
fflush is not defined for input streams; fflush(stdin) does not clear the input stream. Remove those lines from your code altogether.
NEVER NEVER NEVER NEVER NEVER use gets. It will introduce a point of failure in your code. It has been deprecated in the C99 standard, and is expected to be gone from the C1X standard. Replace those with calls to fgets instead.
The one problem that stands out immediately to me is that you've declared add to take a char * and call it as such, but you later define it to take a node *:
void add(char *);
...
char word[20];
...
gets(word); // use fgets instead!!!!
...
void add(node *head)
{
...
}
This is undoubtedly where at least one of your errors is coming from. Go back through your code and make sure that your function definitions match up with your function declarations and that you're calling the functions with the right argument types.
Note that you can place your function definitions before main; the definition also serves as a declaration, so that's one less thing you have to keep straight. In general, I arrange my code so that functions are defined before they are used (at least within the same file); it means my code reads from the bottom up, but it also saves me the hassle of keeping declarations and definitions straight.
